-ser can provide kernel configuration such as tile size, warp size, padding, pipeline, scheduler and epilogue in the config file. For reference please see `./configs/user_provided_config.json`. The Tile engine also has default kernel configuration to expand the range of kernel configuration which is saved in `./configs/default_config.json`.
